Oh man. I wish I could join, but I just don't have enough rack space or amperage to fire up the GPU cluster. 36 cores, 192GB RAM, 24 GTX 680s... damnit. I'm already drawing 11 amps per phase off my 15 amp PDUs.... I'm pretty sure I'll draw more than 8 amps off each PDU for the cluster.

We have a "In-Challenge"-race going on between BOINC@MIXI (#11), TeAm AnandTech (#12) and Polish national Team (#13). We keep changes places in the stats.
Can we recruit some more crunchers?
We need all the power we can get!

It totally varies between cards. GTX550s are particularly sensitive and tend to need to be underclocked. Memory is usually the culprit - GTX 460 768MBs like mine can be nicely overclocked - but shaders can be overclocked too much as well.

Edit: Just saw this in the PrimeGrid chat forum: "chip: the best test is occt gpu, mode - error check". I don't know for sure if it's the best test, but if you get any more failures it couldn't hurt.

First off, I don't think GFN draws any more power than FAH. But maybe you weren't using the GTX 680s on that either?

Oh dear errors? It tends to be with temperature, that is the culprit and mess with the needed calculations and math behind. So yes overclocking might be the problem but it is usually the temperature.
EDIT: And I will have a stats spreadsheet ready in a few hours

Not necessarily. The 448 cores version is essentially a faster gtx 470. Compare your clock speeds to stock clocks here.

I guess it's possible to have a bad WU in GFN, but the chances are extremely low. Stock clock and/or underclock and/or add more cooling (e.g. case fans) and/or turn up your card's fans as high as you can stand them.

Besides the folks running GPUs in this race, has anyone turned in any CPU tasks yet? I'm curious to see how Sandy Bridge/Ivy Bridge and the FX-8000 series CPUs are doing overall. I'm running roughly 80 hours for ~50% completed.

Theoretically, I'll return CPU tasks in 30 - 37 hrs. This is with HT off on an i2600K.

Windows update in the middle of the night last night. Hopefully I didn't miss too much time. The monitors turning on woke my wife up who in turn woke me up asking if I was just on the computers. My response was no, but now I am going to be.

I have 2 gpu tasks waiting for validation. Should have another 2 tonight.
I started late to the game so I'm hoping I can get some cpu tasks in before the deadline.
Have an fx8120 and 2 1055t's going.

I'm also late to the game but better late than never.... haven't run PrimeGrid in many years but this seems like the perfect time to get back on board! Looks like we are in a tight race so even my creaky old GTX 260 is bound to help some.

Hopefully my 3 machines can get the CPU work done in time. Looks like the gpu's are doing well. Might have to put the GTS 450 I lent my parents to use...PG doesn't kill the ability to use the computer like F@H does.
